Table 1: The midfacial morphogenesis score for cultured E11.0 rat embryos for 48h assigned by (I) the formation and mergence of midfacial processes and (II) the degree of MNPs merged each other at the midline, then (I) and (II) were summarized to present their midfacial morphogenesis in all treatment groups (adapted form [26]).
